JACOB HOUSER, OF MEDFORD, OKLAHOMA.

AUXILIARY WATER-HEATER.

To all whom it may concern:

Be it known that I, JACOB HOUSER, a citizen of the United States,residing at Medford, n the county of Grant, Oklahoma, have lnve'ntedcertain new and useful Improvements in Auxiliary IVater-Heaters forSteam- Boilers; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

My invention has relation to water heaters for steam boilers, and itconsists in the construction and arrangement of parts, as will behereinafter described and particularly pointed out in the claim.

In the accompanying drawings,Figure 1 is a plan view of a boilerprovided with my auxiliary water heater; Fig. 2 is a longitu dinalsectional view out on the line 22 of Fig. 1 looking in the directionindicated by the arrows; Fig. 3 is a detail view of a slightly modifiedform of the water heater, showing its intermediate portion built up of anumber of hollow tubes connected at adjacent ends by return couplings.

As shown in the drawings, the numerals 1, 2, 3 and 4 indicaterespectivel the water chamber, heat fines, and smo e box and stack of astationary steam boiler.

5 indicates the auxiliary water heater which is preferably made from onecontinuous piece of hollow tubing communicating at one end with thewater chamber of the boiler extending forwardly on the outside of thesame to a point near the inner end of the smoke box through which itsintermediate portion 5" extends in a zigzag form or fashion. One end ofthe latter formation of said tube is connected to the boiler, as at a,the opposite end thereofbeing bent back and forth laterally in o positedirections with respect to the axis of the boiler to form a plurality ofparallel tubes, the free end of said heater extending out of the frontend of the smoke box and thence rearwardly along the outside of theboiler so that it may be connected with a source of water supply when itis desirous to replenish the supply of water in the boiler. An uprightsupport 6 of preferably inverted U -sha ed form is arranged in andlongitudinal y of the smoke box under the water heater to support ormaintain it in position.

Should I find it desirable in the construction and application of theinvention I may Specification of Letters Patent.

build up the intermediate portion of the heater, or in other words, thatportion extending through the smoke box of the boiler of a number ofhollow pipes or tubes 7 connected at their adjacent ends by returncouplings S. This method of building up the intermediate portion of theheater enables it to be applied with greater facility in position. Theintermediate or zigzag portion of the heater being arranged in the smokebox or in any other suitable position whereby it is subjected to theheating action of the products of combustion from the furnace, ismaintained atahigh degree of temperature as long as there is fire in thefurnace. When it be comes necessary to replenish the supply of water inthe boiler the free end of the heater is connected with the source ofwater supply and the water caused to pass through the entire length ofthe heater before passing into the water chamber of the boiler.

By employing my improved auxiliary heater in connection with a steamboiler the products of combustion are utilized twice in raising thewater to the required degree of temperature, and it necessarily followsthat the fuel consumption is reduced to a minimum.

While I have shown and described my improved auxiliary heater inconnection with a stationary steam boiler, I have done so merely for thesake of this specification, as it may be applied to a locomotive or anyother steam boiler.

I wish it to be understood that my boiler is constructed in sections andat the joints of each section is provided bands I), arranged on theoutside of said joints of the sections and bolted thereto so as toprovide means for securing said sections together, the front and rearplates 10 and 10 respectively, of the heating and smoke chamber areflanged as at 10 so as to overlap the ends of the said heating and smokechambers, said flanges being also provided with bands I), which arebolted thereto and to the flanges of the plates, and to ends of theheating and smoke chambers. Between the heating and smoke chambers Iprovide a )erl'orated flanged partition 10, which reinforces the meetingends of the water and smoke chambers and also serves to support theinner ends of the heat flues 2 in said perforations, the outer ends ofthese lines being secured to perforations formed in the rear plate 10 ofthe heating chamber.

Having described my invention, what I claim as new and desire to secureby Letters Patent, is

A structure of the character described comprising sectional heating andsmoke chambers, an auxiliary Water heater composed of a series of pipeslocated in the smoke chamber having a support for the same, an inletpipe secured to the end of one of said pipes, and an outlet pipe securedto the end of another of said ipes, said sections of heating and smokecffambers having their meeting ends secured together by hands, the outerends of the heating and smoke chambers being provided With flanged latesWhich overlap said ends and having bands bolted thereto and to said endsof the Water and smoke chambers, the plate of the Water chamber beingperforated, a perforated flanged partition secured to the inner surfaceof the water and smoke chambers therein provided With perforations, saidpartition serving to reinforce the Water and smoke chambers and alsoserving as a support for the inner ends of the heating pipes which areconnected to the perforations JACOB HOUSER.
